Customer Ratings & Reviews

This 20W-50 has a fair amount of Zinc in it which help with the flat tappets in my Bike. It also handles the heat very well as I am running a big 1854cc V-twin . I find that this stuff stays in a better color range even after 1000's of miles. The factory brand will look dark brown in 300 miles after a long days ride , not this 20W-50 Amsoil. Bike also uses a wet clutch oiled by the same oil and it holds up well.

Great product, highly recommend

It works and my oil analysis prove it

Great oil! Great service. Highly recommended. CK

Great product/ cost for my patrol bike would not go back to Harley oil.

Do your own research, I did, and the answer for my Harley was Amsoil. That was 12 years ago when I bought my latest bike and nothing has changed. I beleive this is the best oil you can put in a bike!

Awesome product

I use amsoil for all my bikes it just works and keep them running strong

I’m a customer for life I’m sold on this oil I ride very very hard red line all the time and daily driver lot of miles at 4000 miles the oil look like new sn3 lol

I have seen the testing data on Amsoil products and believe their products are top notch.

Keeps my Vision running smooth.

Fantastic oil and products. Came highly recommended by friends and I am glad I switched to AMSOIL.

Good for 5000 miles. Keeps the engine running smoothly.

This Oil Works great, When On the Run For The Wall 2025 on my 2020 Harley Road Glide Limited and loaded it down and drove over 6800 Miles on a fresh oil change, and Oil still looked dam good. Only oil I will use on my motorcycles, Cars, Truck and boat. Love It Thanks for a great Oil

Great delivery time Great oil

Have had no problem with the oil very little oil burn off between oil changes (6000-8000km)

Great product does keep engine heat down on summer days

I changed from HD Synthetic Oil to Amsoil and I'm glad I did. After 5000 miles compared to the HD oil, you can visually see the difference. HD oil has always come out black and you can tell that it's lost a lot of it's life. I changed out this last go around from Amsoil to Amsoil and there was still plenty of life left in the oil. The difference in color and feel of the used oil was a big difference from the HD oil. Definitely recommend this oil. I started running Amsoil in all of our vehicles a few years ago.

I use this in all three of my Harley’s. It’s a better way to not have to open 4 bottles of oil when doing oil changes and saves a little money by bulk purchase

Best oil. Get the kit.
